[ 1/1Inequality]
    Assignment:Find the solution set of inequality ((3√3)/2(5/√3+6l+30)^2-127π×〖2.5〗^2)/((3√3)/2(5/√3+6l+30)^2) ≥0.13 .
    Question type: Inequality
    Solution:
    The inequality can be reduced to 1 inequality：
         ( ( 3 * √ 3 ) / 2 * ( 5 / √ 3 + 6 * l + 30 ) ^ 2 - 127 * π × ( 2.5 ) ^ 2 ) / ( ( 3 * √ 3 ) / 2 * ( 5 / √ 3 + 6 * l + 30 ) ^ 2 ) ≥0.13         (1)
        From the definition field of divisor
         ( 3 * √ 3 ) / 2 * ( 5 / √ 3 + 6 * x + 30 ) ^ 2 ≠ 0        (2 )

---

    From inequality(1)：
         -6.266509 ≤ l ≤ -4.695742
    From inequality(2)：
         l < -2740563/500000 或  l ＞ -2740563/500000

---

    From inequalities (1) and (2)
         -6.266509 ≤ l < -2740563/500000 或  -2740563/500000 < l ≤ -4.695742     (3)

---

    The final solution set is :
         -6.266509 ≤ l < -2740563/500000 或  -2740563/500000 < l ≤ -4.695742
